Bookmark in mathematical formula

[ManMasterDevelopment]

I have a word document with mathematical formula. In this formula there is a bookmark and I’m trying to change the bookmark Text.

Here is a sample project:
TestAppCore.zip (256.5 KB)

Steps to reproduce:

1. Open project in Visual Studio
2. Set an Aspose licence (important)
3. Run the app and click a button

You should get exception. The problem is that bookmark we try to change is in the mathematical formula.

How can I change it text?
If you need more info, please let me know
Thanks
